I have woken up suddenly with hives before and that was the onset of my chronic urticaria. Maybe you might want to eliminate the stuffs that you mentioned and then see if you improve. Then come in contact with the stuffs one by one and see if any are really causing you trouble. You can take an antihistamine or benadryl to help with the itching and hives. If it doesn't go away within weeks, and it's really bad, it's best to consult with a dermatologist or allergist. good luck! :angel:
